Q1

A body is projected vertically upwards from the surface of earth with a velocity sufficient enough to carry it to infinity. The time taken by it to reach height \(h\) is _______ s.

a

\(
\sqrt{\frac{2 R_e}{g}}\left[\left(1+\frac{h}{R_e}\right)^{3 / 2}-1\right]
\)

b

\(
\frac{1}{3} \sqrt{\frac{2 R_e}{g}}\left[\left(1+\frac{h}{R_e}\right)^{3 / 2}-1\right]
\)

c

\(
\frac{1}{3} \sqrt{\frac{R_e}{2 g}}\left[\left(1+\frac{h}{R_e}\right)^{3 / 2}-1\right]
\)

d

\(
\sqrt{\frac{R_e}{2 g}}\left[\left(1+\frac{h}{R_e}\right)^{3 / 2}-1\right]
\)
